Description

Auto-translated from German

HWW operates its largest waterworks at the Granetal dam. Due to changed space and area requirements and new building security requirements, the existing operational building, which previously housed administration, control, and laboratories of the waterworks, is no longer up-to-date. It is therefore planned to completely renovate the building. For this purpose, a demolition of the roof story (former laboratory ventilation technology) and an energy-efficient renovation of the facade (modern thermal insulation, optimization of window areas) are planned. The ground floor will house the workshops and changing rooms. The 1st and 2nd floors will accommodate offices and social rooms in the future. The 3rd floor will remain as expansion reserve. The control room will be housed in the connecting corridor to the waterworks. A carport and storage hall will be built on the area of the former exhibition wing to cover the demand for storage space and parking spaces. The laboratories were already relocated to a separate building in a previous project. Planning will be carried out using the BIM method.
